Don't forget to enter LEGO Ideas' latest GWP challenge

Time is running out for the chance to help design a future LEGO Ideas gift-with-purchase in the platform's search for a secret-hiding model.

Those who haven't started their entry for LEGO Ideas' latest GWP challenge will want to do so as soon as possible. The deadline to submit something for the Hidden Secrets contest is coming up on July 29.

The brief for this challenge is to design something with some kind of secret, and it may well be a future gift-with-purchase. The most important rule to be aware of is that no IPs are allowed, which includes the LEGO Group's IPs, too. The maximum piece count for your model is 250 elements, and it must have no more than two minifigures.

The grand prize for the challenge, as well as seeing your model become an official set, includes 10 complimentary copies, credit and a bio as the LEGO Ideas Fan Designer in the set materials, 10351 Sherlock Holmes Book Nook, 21362 Minerals Collection, and 21358 Minifigure Vending Machine. The grand prize package also features a mystery prize.

There will be a fan vote to determine the winner starting from August 11, and any users who make it to this phase will win 10351 Sherlock Holmes Book Nook and 21362 Minerals Collection.

Enter the challenge before July 29, and you may well be a future LEGO Ideas fan designer. You'll want to allow extra time for resubmission, in case something in your entry is not allowed. Click here to visit the contest's page for the full rules and submission process.
